Without going for the stupidly over-the-top ones (I don't care how much Simon might love food and drink; I for one am not going to pay £200 for a bottle of anything), I'd go for the three main Glens:
Glenlivet
Glenmorangie
...and if all else fails...
Glenfiddich.

None of that nasty stuff with an extraneous "e" in the name.

There are quite a few lovely regional ones too, but I'm damned if I can remember the names.
